To ALL WHOM IT MAY CONCERN:

Be it known that I, E. K. HARVEY, of Quincy, in the county of Logan, and in the State of Ohio, have invented a new and improved Combined Roller and Revolving Harrow; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. v

Figure 1 is a side elevation of my machine, and

FignreQ a plan or top view thereof.

The frame of the machine is square, or nearly so, and is composed 0B the side rails A A, connected by the cross-ties B B. l

C is the tongue, to which the team is attached, and a a are caster-wheels, supporting the rear end of the machine.

D is a large cylindrical roller, the length of which is nearly equal to the internal width of the frame. This roller is-placed within and near the front "of the frame, and at each end are journals, which have their bearings under the side rails A A, as shown in fig. 1. To each end of the roller are rigidly attached the spur-wheels E,

the roller andwheels havingthe same centre of'motion.

F-is a shaft, extending acrossthe frame, in the rear of and parallel to the roller, and has its bearings under the side rails A. On this sha'ft,- just inside of the side rails, are toothed wheels G, somewhat smaller than the wheels E on the roller, with which they gear.

In the rear of and parallel to the shaft E, is the harrow H, which is a cylinder, of the same length as the roller D, and of about one-half its circumference. In this cylinder the teeth Z: are inserted, so as to stand out in rays around it. On the ends of the barrow, and having the same centre of motion, are the toothed wheels I, somewhat smaller than the wheels Gwvith which they gear. The journals, on which. the harrow revolves, extend through the cam-slots a, in the housings (2, which are secured to the under side of therails A, and have their bearings in'the ends of the spanner e, on the outside of the frame. Apart of the spanner e is represented as broken away, to show the cam-slot in the housing, which would otherwise be hidden. 7 I

Near the centre, on the-rails A A, are secured the upright standardsff, which support the horizontal rock-shaft g. To the rock-shaft is rigidly attached the lever 7t, which extends forward past and in close proximity to the drivers seat 1', and is adjustable, by means of teeth, in the upright standard m. To the centre-of the rock-shaft, and extending backward, is an arm; n, with a hooked .end, to which, by means of a link, the spanner e is suspended. I

' 13y lowering the leverit, the spanner'e'will be elevated, carrying with it the barrow, the cam-slots 0 being so arranged as to unship the wheels I when the harrow is raised from the ground. The harrow may be retained in any position desired, by means of the lever k and toothed standard m, and the machine thus used simply as a roller.

This machine is well adapted to the preparation of ploughed ground for receiving seed, the roller levelling the ground, and the barrow pulverizing it, and leaving it in proper condition for receiving the seed. It may also be used for covering seed after it has been sown. Grounds from which crops have recently been taken, and where deep ploughing is not necessary, may be prepared very rapidly, with this machine, for receiving the seed for another crop. Its merits are so obvious that any farmer who sees it will comprehend its utility, and understand how and when to use it.

Having thus described my invention, \vhat'I claim as new, and desire to secureby Letters Patent, is

1. The lcver'h, arm n, and spanner e, in combination with the barrow H, substantially as described.

2. The hnrrow I-I, housings d, and spanner e, combined and operating substantially as described.

In testimony that I claim the above-described combined roller and revolving barrow, I have hereunto signed my name, this 2d day of March, 1868. I

E. K. HARVEY.
